Paul Duffin a0843f6a6f Differentiate between cc library and binary
The cc library and cc binary (and other cc module types) are all
instances of cc.Module. So, to differentiate between them and make
sure that only appropriate library instances can be added to
native_shared/static_libs this adds a special sdkMemberTypes field to
Module which if set specifies the SdkMemberTypes the module supports.
If it is not set then the module type cannot be used in the sdk at all.

Corrects an issue with one of the tests where a prebuilt cc
library was added to the sdk instead of a source cc library.

Adds a new test to ensure that cc_library_(shared|static)_host module
types work with the sdk as well and another test to ensure that
cc_library can be used as either.

Paul Duffin 57b9e1da75 Improve handling of generated include dirs
The exported include dirs includes both source and generated
directories (e.g. containing aidl generated headers). The latter are
always arch specific so if they are present they make all the include
directories arch specific.

This change separates the source and generated include dirs so that
the source include dirs (which are probably not arch specific) can be
optimized separately from the arch specific generated include dirs.

The FilterPathList() func was refactored to extract the more general
FilterPathListPredicate() func.

A number of tests needed to be updated to reflect the more optimal
snapshot creation.

Paul Duffin a7cd8c8344 Generalize common property extraction
Previously, code that attempted to optimize the generated .bp rules
treated the properties structure as a single entity. So, a single arch
specific value would cause all properties to be treated as arch
specific. Also, that code was specific to one structure type.

This generalizes the optimization to work with any properties structure
which will be helpful for other multi-variant module types. It also
treats each property separately.

The hasArchSpecificFlags field has been removed from nativeLibInfo and
a commonProperties field has been added instead into which the common
values will be found. File path creation that conditionally prefixed a
path with archType has been replaced with general code that relies on
archType being "" for common properties and filepath.Join(..) ignoring
empty string components.

The common and arch variant properties are always processed. The first
within the context of the .bp module's property set and the latter
within an arch specific property set. There are always some properties
that are arch specific, e.g. outputFile, so there is no need to worry
about an empty arch property set being created.

The archSpecificNativeLibInfo type was renamed nativeLibInfoProperties
as it may not be arch specific.

The printExportedDirCopyCommandsForNativeLibs variable was renamed to
addExportedDirCopyCommandsForNativeLibs as it no longer does any
printing.

Paul Duffin 9ab556fd8e Added support for using static libraries in sdk snapshot
Parameterized the cc.librarySdkMemberType to allow it to support
both static and shared libraries. Created two instances, one for shared
and one for static libraries. A follow up change will add support for
libraries that can be both.

Added *librarySdkMemberType to nativeMemberInfo as information from
there is needed when generating the snapshot.

Made organizeVariants() func a method of *librarySdkMemberType so that
it can initialize the new field. Moved it to be with all the other
methods of that type.

Added host and device tests for the new module type.

Inseob Kim d110f878a7 Fix generated headers of snapshot
For VNDK snapshot and SDK snapshot, deps files have been used to capture
generated headers. But exported deps might contain intermediate phony
files instead of actual header files, which are for optimization of
ninja. To correctly capture all headers, exported generated header files
are gathered separately.

Paul Duffin 1387957727 Parameterize the sdk member processing
Extracts the type specific functionality into the SdkMemberType
interface which has to be implemented by each module type that can
be added as a member of the sdk. It provides functionality to add
the required dependencies for the module type, check to see if a
resolved module is the correct instance and build the snapshot.

The latter was previously part of SdkAware but was moved because
it has to be able to process multiple SdkAware variants so delegating
it to a single instance did not make sense.

The custom code for handling each member type specific property,
e.g. java_libs, has been replaced with common code that processes
a list of sdkMemberListProperty struct which associates the
property (name and getter) with the SdkMemberType and a special
DependencyTag which is passed to the SdkMemberType when it has to add
dependencies.

The DependencyTag contains a reference to the appropriate
sdkMemberListProperty which allows the resolved dependencies to be
grouped by type.

Previously, the dependency collection methods would ignore a module if
it was an unsupported type because they did not have a way of
determining which property it was initially listed in. That meant it
was possible to add say a droidstubs module to the java_libs property
(and because they had the same variants) it would work as if it was
added to the stubs_sources property. Or alternatively, a module of an
unsupported type could be added to any property and it would just be
ignored.

However, the DependencyTag provides information about which property
a resolved module was referenced in and so it can detect when the
resolved module is of the wrong type and report an error. That check
identified a bug in one of the tests where the sdk referenced a
java_import module (which is not allowed in an sdk) instead of a
java_library module (which is allowed). That test was fixed as part
of this.

A list of sdkMemberListProperty structs defines the member properties
supported by the sdk and are processed in order to ensure consistent
behaviour.

The resolved dependencies are grouped by type and each group is then
processed in defined order. Within each type dependencies are grouped
by name and encapsulated behind an SdkMember interface which includes
the name and the list of variants.

The Droidstubs and java.Library types can only support one variant and
will fail if given more.

The processing for the native_shared_libs property has been moved into
the cc/library.go file so the sdk package code should now have no type
specific information in it apart from what is if the list of
sdkMemberListProperty structs.

Colin Cross 6d88dbad0e Reorder local and global flags
Native compiler flags are currently applied in approximately:
global cflags
local cflags
local include dirs
global include dirs
global conlyflags
local conlyflags
global cppflags
local cppflags

This means that a flag that is enabled in the global cppflags
cannot be disabled in the local cflags, and an Android.bp author
must know to disable it in the local cppflags.

The previous CL split the global and local flags into separate
variables.  Rearrange the order that the variables are applied
to be:
global cflags

We are mixing both the global and local cflags into a single
variable, and similar for conlyflags and cppflags, which
prevents reordering them.  This CL prepares to reorder them
by splitting the global and local cflags into separate variables.

Martin Stjernholm 279de572d7 Treat libclang_rt.hwasan-* the same way as the other Bionic bootstrap libs.
Ensure that it ends up in the bionic/ subdir in the Runtime APEX and is
symlinked from /system/lib(64). That makes it available in the default
(platform) linker namespace and no longer requires it to be accessible
through the runtime namespace. All this makes it consistent with how the
other Bionic libs are handled, and avoids the need for various special
cases in ld.config.txt files (to be cleaned up later).

With this there might no longer be a need for a linker namespace for the
Runtime APEX, and we could consider removing the kludge with the
/apex/com.android.runtime/${LIB}/bionic subdirectories and the special case
in getCopyManifestForNativeLibrary in apex.go. However, keeping it calls out
the special treatment of those libraries, and allows a namespace to be added
again if necessary.

Pete Bentley 803e161ac9 Introduce inject_bssl_hash library property.
external/boringssl needs to run a tool on a shared library, but
cc_genrules currently don't support shared libraries as inputs
or outputs.  Use a property to trigger the desired behavior for
now.

Jiyong Park ee9a98d88e Build native coverage variant of APEXes when needed
When the native coverage is enabled, APEXes (and files there) are built
for native coverage as well.

Inseob Kim ae55303f36 Include headers and props to VNDK snapshot
For all vndk snapshot libraries, header files exported by the libraries
will be included to the snapshot. Android.bp will contain necessary
information to link against/install vndk snapshot libraires:
export_include_dirs, export_system_include_dirs, export_flags, and
relative_install_path.

Hsin-Yi Chen 5348964723 Add tags to the list of lsdump paths
This commit adds tags, such as NDK, VNDK-core, and PLATFORM, to
LSDUMP_PATHS. The script updating the reference ABI dumps uses the tags
to determine the directories where the dumps should be created.

Test: make findlsdumps

Vic Yang 6cd1be8993 Add sort_bss_symbols_by_size property for shared libs
If sort_bss_symbols_by_size is true, a shared library is built twice.
The first build generates an unsorted output file, which is used to
generate the symbol ordering file.  The output of the second build is
a shared library with its bss symbols sorted by their size.

With this, the only user of symbol_ordering_file, libc, is migrated to
use the new property, so we remove symbol_ordering_file support as well.

Bug: 135754984
Test: Build and check the resulting libc.so has its bss symbols sorted.
